BARACK Obama joked that he had “tucked up” David Cameron in the presidential bed after offering him a chance to rest on Air Force One, it emerged yesterday.

The episode was recounted by the Prime Minister as evidence of the strength of Britain’s “special relationship” with the US under his leadership.

Mr Cameron was last week hailed as the first foreign leader to fly on the US Presidential plane after Mr Obama invited him to a basketball match in Dayton, Ohio as part of the PM’s official visit to America.
